INHLER.

SPECIFICATION forming part of Letters Patent No. 355,309, dated January4.-, 1887.

Application led April 29, 1886; Serial No. 200,505. (No model.)

To all whom it may concern:

,Be it known that I, ALLEN R. Foorn, of Philadelphia, county ofPhiladelphia,and State of Pennsylvania, have invented anew and usefulImprovement in l'nhalers, of which the following is a full, clear,V andexact description, reference being had to the accompanying drawings,making part of this specitication.

My invention relates particularly to that class of inhalers used forvolatile inhalents; and f it consists in the combination, with a singlereceptacle, of several tubes, as hereinafter described, by which asingle inhaler can be made to serve as an active inhaler when thepatient draws the vapor into his own nostrils or throat, and as apassive inhaler by which the vapor is blown out by some one other thanthe patient. I attain these objects by the mechanism illustrated in theaccompanying` drawings, in Whichy Figures 1, 2, and are tubes for activeinhalation, Fig. l being a throat-tube, Fig. 2 a supplytube to conveyairnear the bottom of the reservoir,and Fig. 3 anasal tube. Figs. 4, 5, and6 are tubes for passive inhalation, 4 being' the supply-tube, to which ahose wit-h a bulb can be attached. 5 5 5 are tubes for directing thevapor to an yrequired point. 6 is one particularly designed for use indiphtheria. Fig. 7 shows the receptacle or bottle furnished withstopper, with perforations to admit anyone of the abovementioned tubesat will. A sponge is carried by a bent wire and attached t the underside ofthe cork. Fig. 8 shows the bottle provided withthe nasal tube andthe air-supply tube eXtended to pass the air through the contents of thebottle. Fig. 9 shows the bottle provided with active-inhalation tube andbeing used. Fig. 10 shows the same bottle fitted Withthe interchangeabletube for passive inhalation.

It is not claimed that either of these methods of inhalation is new,'.orthat, separately considered, the tubes are new; but with all the olddevices known up tothe time of this invention' different instrumentshave to be bought for the different sorts of application in active andpassive inhalation.

By my invention all the different tubes' needed are furnished of thesame size, so that they are interchangeable, and any and all fit throughthe acid before it passes the ammomum-sponge. f

For passive throat-inhalation, the bottle is to be used either with tubel alone and with l and 5, or with tubes/t and 5, the former beingcoupled by a short hose to the usual rubber air-forcing bulb. In thelatter case the air is forced downward past the ammonium vsponge andthrough the acid before being driven out of the end of tube 5. The bentexit-tubes 5 give direction to the current. It may also be coupled witha short hose, at the end of which is a duplicate of tube 5. This latterform is particularly adapted for use in diphtheria, whenit is notdesirable that the nurse should come in close I contact with thepatient. rlhe end of tube 5 could be made, of course, to enter the mouthor nostril of the patient; but this is not needed, as the air soonbecomes iilled with clouds of crystals of nascent chloride of ammonium.

kFor use with menthol, a dram of mentholcrystals can be put dry into thereservoir of the inhaler and two ounces of water at 7 0 to 80 Fahrenheitadded. It will then be ready for activeinhalation or passive with theproper tubes.

Tubes Nos. l and 4- can also be utilized for drinking-tubes. Y

lThe stopper of the inhaler-bottle is made of wood coated with anacid-proof enamel.

The usesto which the bottle, with its six different sorts of tubes,rnaybe applied are only limited by the inventive genius of the physician.Vith the present apparatus all the treatments can be readily made whichformerly required the purchase of several complete instruments, and thusnot only expense but space is econornized, and also time in preparingand charging different instruments as they become necessary at differentstages of a treatment.

TOO

With the set of tubes described, used singly or in differentcombinations, all currents of air can be produced and controlled thatcanbe used in active (throat or nasal) or passive inhalatiou. Further, theair-currents can be made to pass'over or through the contents of thevessel or reservoir, thus adapting the apparatus to be used with anyvolatile inhalent.

WhatI claim as new, and desire to protect by Letters Patent, isl 1. Theinhaler-vessel with the double-oriiced cork or stopper, combined withthe set of tubes 1, 2, 3, 4, 5, and 6, all as and for the purposedescribed.

2.' Theinhaler-vessel,combined with theperr 5 forated wooden cork coatedwith acid-proof enamel and carrying the sponge and tubes, allsubstantially as and for the purpose specified.

3. The double-orced enameled acid-proof cork or stopper, combined withthe inhaling 20 Vessel and tubes, substantially as and for the purposespecified. f

In testimony whereof I `have hereunto set my hand this 28th day ofApril, A. D. 1886.
